So i only started using reasonably good headphones within the last year, so im still rather inexperienced. At the moment i use Sennheiser HD 238 Precision cans for out and about and around campus. The problem is they leak noise a lot being open and supra-aural and all and i think its time to get something new. I like the look of the 428's, they're quite cheap and seem to have good reviews, only thing im worried about is how easy they are to drive and if my ipod would make a meal out of it. I tried the 448's in a store and they sound great, but were a little shy on volume with my ipod.
I was also looking at the 418's but they dont appear to sound as good? Another option i was considering were the AKG K518's as they are tight fitting and have pretty good noise isolation. Anyone have any insight to help me choose? Other possibilities are welcome too.
